Design and Implementation of Smart Chiller System using AVR Microcontroller

Abstract

Chiller is the system to maintain the temperature of any reservoir at critical point and  Operate the system in defined range of temperature. It is mainly used in the machines which gets heated and due to which the machine gets damaged. Mainly the present work is done for preventing  diamond cutting laser diodes from damage. AVR microcontroller is used so that it is cost effective. It continuously keeps the water cool by Monitoring the water flow, level and temperature continuously. Control a pump of motor and compressor. Main task is to operate a solenoid valve for controlling the flow of gas. we set the temperature range and critical point of temperature using LCD and button mechanism. It has been made wireless using zigbee so that wireless monitoring from 1km distance is possible also the GSM 900 module has been attached to inform about the fault occurred in the system through message. Here, we are doing monitoring through lab-view software and programming has been done in micro C software.
